The cutters 33 are-normally statzonary -and are supported in their elevated positions by relates to note sheet cutlight' springs 3.-3

To whom it may concern? Be it known that I, VVALTER R. ORIPPEN, States, residing at Cambridge, Massachusetts, have invented. certain new and useful Improvements in N ote-Sheet Cutting Apparatus, of which the following-is a full, clear, and exact description.-

- This invention ting ap aratus for: cutting note sheets for use wit music playing instruments.

Above the series of cutters '(an desired ong other advantages are simplicity number of which may be provide to form with the keyboard of a piano,

The range of vibration oigthe striker-bar is insufficient to enga e the cutter-heads directly, but when it is esiredto actuate any articular cutter, the same is coupled witlrt e striker-bulin the following uni ue manner: When a certain key is struck, it operated neumatically, (or in any equivalent manner-l means for introducing between the cutter-head andthe vibrating striker bar a suitable coupling device 6. their retracted positions, t

Fig. 4 is arela- .tively enlarged sectional view of that part rovetl apparatus which is connected to t ekeyboard of the piano. Fig. 5 is a diagrammatic view of certain details of construction, showing certain parts in. section and in elevation. Fig. 6 is a viewof a portion of a note sheet, illustrating perforations therein, such asmay be cut with my improved apparatus. Fig. 7 is a sectional view of a modification of a certain detail.

While it maybe understood that various modifications may. be made in my invention, 1 will proceed to describe more particularly that form shown in the drawings, which is, I believe, of preferable construction. 1 represents a blank sheet of paper leading from the roll 1 a to the cutting apparatus,

in the space between'the vibrating strikerbnr and the cutters, so that the latter will partake of the. rapid, of the stn'ker-bar. By operating certain couplers .at the proper timc, the desired cutters 'can be selected to operate upon the sheet 1, and perforatethe same at the proper time and to the proper extentfi To guaran as shaft 5 is rapidly rotated, the striker-bar vibrating movement as J W'henthese cou lers 66 are in e bar 4 will have i no effect upon the cutters, but when ad-" vanced, thcsecouplers will, so to speak, fill-10 i) lieve the spring 3 of this burden, I provide the chamber 10 may be retractor bars 4-4 which are carried by the vibrating striker-bar and extend-under thehead of each cutter, so thaton the upward movement-of the striker-bar any cutter which is then being operated is bound to be withdrawn from the die and paper. The couplers 6-6 are preferably light bars placed edgewise and guided at their forward ends in suitably slotted plates '6 These coupler bars are suitably connected, as by pivots, at their rear ends, to small power'pneumatics 7-7, or equivalent devices. These pneumatics are normally disended as by sprin s, such as 7*, and when distended the couplers are held in their retracted or idle position. 1

88 are valves to control the operation of the pneumatics. These valves put said neumatics respectively in communication with an exhaust on the one hand, and the atmosphere on the other hand. Normally thesepneumatics 7 are open to the at1nosphere, as shown in Fig. 3, but when the Valves 8 are shifted they are put in communication with the exhaust, as later 1'c.

ferred to, whereby collapse is effected to move the couplers.

he up er part of the die 2 is rounded or arched alter the manner of an ordinary tracker-board of piano-player type, thus preventing injury to the paper. 11 front of and to the rear of this die 2 are r'olls 9 $J located at a lower elevation than the die, so that the sheet will be given a serpentine course' (as best seen in Fig. 3) thus preventing the formation of wrinkles in the paper as it traverses the die. Directly under the die is a vacuum or suction chamber 10 (Fig. 3) connected through pipe 10 with a tank 11 (Fig. 1), partially Iilled with water. The suction or vacuum is maintained tl'rrough pipe 11 (connected with. a suitable exauster)'the free end of which extends into the tank 1]. At each end of the chamber 10 is an admission-port, )referahly controlled by valves 12*]2. W men in operation, the an entering )ast valves 12]2 moves toward the out et pipe 10, carrying with it any chi )s or cuttings punched from the paper. .lhese chips or cuttings traverse down the pipe 10 and collect in the water in the tank 1 1. By thus removing the chips, clogging is avoided. The speed of the air entering the valved passages at the ends of controlled by regulating the valves 12]2. Furthermore, by having these valves at this point no wasteful volume of air need be admitted.

In the drawings 1 have shown the neuniatics 7'Z arranged in rowsor banks there being several pneumatics in each bank). These banks are arranged in two groups or the shaft 5 may sets which stand on opposite sides ofthe cuttcl' die. By this means great compactness and accessibility of parts is afforded, for to remove any particular pneumatic, it merely requires the removal of one row, instead of the entire set. The length of any particular note perforation to be cut is unlimited; in other words ,"the movement of the cuttermay be so rapid as to produce in ellect a continuous cut. I

Since the paper moves in a direction at right angles to the movement of the cutter, 1 provide, as indicated above, an intermittent feed, so arranged that the paper will be given a forward movement only during that period when the cutter is lifted, no matter how short that period may be. This I accomplish by 7 means of a clutch 14 of the ball type, carried an oscillating arm 14 having a bearing This arm 14 eccentric 14 b at one end of the feed rolls 15. is oscillatedby means of an mounted on main shaft 5. The eccentric 5' for the striker-bar and the eccentric 14 for the paperfeed rolls are so placed relatively to each other that the advance the feed rolls will occur during that period when the cutter is lifted or disengaged from the note sheet. The link 14, between the paper feed eccentric 14 and the clutch operating arm l l ymakes an adjustable connection (see Fig. 2) with said arm 14",

whereby by moving said connection, nearer.

to or farther away from the axis of the clutch 4, the length of each feeding impulse may be modified at will thus the more remote the connection, the shorter will be the feed, and successive punching will intersect and form an uninterrupted slot or cut of any desired length. 011 the other hand, this connection may be so near the axis of clutch 14 that successive )unches will be separated to a greater or less egree, as desired The die construction is such, and its position in the frame of the machine is such, that by removing a few ordinary holding-screws (not shown) the die and all the punches carried thereby may the main frame (see Figs. 2 and 3). The die proper may be made up of one or more sections, as desired.

be loosened and lifted out, together with the strilcewbar and the cutter retractors.

The frame of the machine is preferably made in two sections, 25 and 25 so that it can be divided on a median line under the Jnain shaft If (Fig. 2), the bearings for the latter being carried by either section, dcsired, but as shown in the drawings by section 25 (Fig. 1). The coupler guides (i -45 y be fi d by these frame sections, so

that when the nmchineis assembled thecou )lers will always be pro fcrly alincd and gui ed.
